  • Patent Literature 1 JP S57-192310 A discloses that a hair dye composition characterized by containing a silicone derivative is excellent in a concealing power and a dyeing and coloring power without increasing the dye/pigment concentration in the composition, and additionally can deepen the color tone of the dyed hair.
  • Patent Literature 2 JP 2007-512388 A discloses use of an aminosilicone as a method of optically improving the perception of the color of artificially colored hair.
  • the present invention relates to the following [1] to [7].
  • a cosmetic composition containing (A) a silicone film-forming agent, (B) a high-molecular-weight organopolysiloxane having a degree of polymerization of 2,350 or more and 20,000 or less, and (C) an organopolysiloxane containing a cationic group other than the component (A) and the component (B), wherein the total content of the components (A) to (C) is 2% by mass or more and 50% by mass or less, and the content of water is 10% by mass or less.
